Cameron, who has
promised a referendum in 2017 if he is re-elected in May, said
the chance of a vote this year would be “pretty
slim.”

“I've said there will be a re-negotiation and then a
referendum – obviously the sooner that re-negotiation can get
done the better and quite frankly the chances of doing that
inside 2015 after an election in May is pretty slim,” he
told ITV's Good Morning Britain.

“I'm going to spend the next 50 odd days campaigning for a
Conservative majority government. I think it can be done. If I
fall short you can ask me the next day what I'll do about
it.”

Cameron has promised to renegotiate Britain's relationship with
the EU, as many Eurosceptic are leaning towards the anti-EU UK
Independence Party (UKIP).

“And yes, that includes my German wife. They are eligible to
vote in European elections, but they should not have the right to
decide on Britain's future in the EU. It may be that that would
require us to do battle with the European Court of Justice – but
so be it.”

EU President Donald Tusk warned on Sunday that Cameron's plans to
amend EU treaties to create a new deal for Britain in Europe were
“mission impossible.”

“My intuition is that treaty change is close to mission
impossible today because it's not only about rationality, about
good argument,” Tusk told the Guardian.

“We need unanimity between 28 member states, in the European
parliament, in 28 national parliaments in the process of
ratification. To say that it is a Pandora's Box is too
little.”

With less than two months to go before the general election, the
Tories are two points ahead of the Labour Party (31 percent and
29 percent respectively) according to the latest Lord Ashcroft
opinion poll.
